Corsair Hydro Series H70 CPU Cooler Review

Although there were previous entries in the field, Corsair's Hydro Series H50 all-in-one sealed liquid cooling system was one of the first that actually worked, in the sense of being easy to install, reliable, and most importantly offering performance competitive with good air coolers while being quieter than most of them. The H50 became very popular and spurred competition from other vendors. The Corsair Hydro Series H70 improves upon the H50 design with a new pump and a much thicker radiator equipped with dual fans. It should offer significantly better performance than the H50, and Benchmark Reviews puts it to the test against a collection of air and water coolers to see how it compares.

Since all retail CPUs are boxed with perfectly good coolers (which are pretty quiet), the main reason to buy an aftermarket cooler is its performance when your processor is overclocked. (There might be some who buy coolers based on the aesthetics of their appearance through a windowed CPU case, but we'll assume they're in the minority.) But while performance is certainly the main criterion, other factors must be taken into consideration as well, such as noise, size, and price. The ideal cooler keeps your processor at or near ambient temperature, is silent, free, and unfortunately doesn't exist. Manufacturers vary the performance, noise, size, and cost factors of their products to address different segments of the market.


Corsair made their reputation in the enthusiast market with their memory products, which offered excellent performance and impressive visuals (who else sells colored accessory fins for their memory modules?), and has begun branching out into other areas with some notable successes such as the original Hydro Series H50 and the award-winning Obsidian 800D case. They also sell power supplies and USB and SSD drives.
